Capt Joes home study program

Is it just me or is this program severely lacking in detailed info? The guy says he will email you back with problems, but I have only received one mail outta 5. Anyone can point me towards a better program to learn compass error by azimuths would be appreciated. I have pretty much got the rest of the Terrestrial stuff , except that. Thanks to all. Going for the 1600 masters NC.:confused:

I did it with Bowditch. If you want to do it on a computer go here. :wink:

AND BOWDITCH I & II, go straight to formulas don’t waste your time with the229 sight reduction tables.

Gracias mi amigos.
